Control pym2149 (via Lurlene) or FoxDot using Vim

Install

These are generic installation instructions.

To use, permanently

The quickest way to get started is to install the current release from PyPI:

# Tested on Linux and Mac:
pip3 install --user Concern

You will also need one of the following backends.

FoxDot backend

# Simply install, and Concern will use it:
pip3 install --user FoxDot

pym2149 backend

# Install as usual:
pip3 install --user pym2149

# Tell Concern to use it instead of foxdot:
echo Concern consumerName = pym2149 | tee -a ~/.settings.arid

To use, temporarily

If you prefer to keep .local clean, install to a virtualenv:

python3 -m venv venvname
venvname/bin/pip install Concern
. venvname/bin/activate

To add a backend, substitute pip install for pip3 install --user above.

To develop

First clone the repo using HTTP or SSH:

git clone https://github.com/combatopera/Concern.git
git clone [e-mail]:combatopera/Concern.git

Now use pyven's pipify to create a setup.py, which pip can then use to install the project editably:

python3 -m venv pyvenvenv
pyvenvenv/bin/pip install pyven
pyvenvenv/bin/pipify Concern

python3 -m venv venvname
venvname/bin/pip install -e Concern
. venvname/bin/activate

Commands

Concern

Vim-based live coding environment.

Usage

FoxDot

# Any arguments are passed to vim, here we discover the FoxDot demo directory:
Concern "$(python3 -c 'from pkg_resources import resource_filename; print(resource_filename("FoxDot", "demo"))' | tail -1)"

• FoxDot is running in the right hand third of the screen
• Send code to FoxDot by typing backslash followed by ]
  • This will send the smallest top-level suite under the cursor
  • The backslash is actually your Vim leader key
• Use visual mode to send multiple top-level suites at once
• Use backslash enter instead of backslash ] to send from cursor to the end of the file
• Use backslash q to quit all of Vim, FoxDot and GNU Screen

pym2149

# GitHub trick to download some files to play with:
svn export https://github.com/combatopera/pym2149/trunk/contrib

# Load a non-trivial tune written in the Lurlene live coding language:
Concern 'contrib/Lemmings 2 Tune 6.py'

• Once pym2149 has initialised, type backslash enter at the top of the file to send the whole program
